In general, there is not a lot of difference between one manufacturer and another any longer. If a VFD does not do most of what people want them to do, they don't survive, so 99.99% of all VFDs do what 99.99% of users want. Mitsubishi has decent quality and depending on where you buy them, decent application support.
